This invention relates to combination clocks and calendars.

The main object of the invention is to provide a clock and calendar of the rotary type in which all the moving parts, including an hour and minute indicating drum, and day of the week, month and day of the month indicating drums, and means for actuating same, are enclosed within a casing provided with openings which permit observation of portions of said drums.

Another object is to provide manually operable means and automatically operable means! for actuating the clock and calendar drums.

Another object is to provide means operatively connected with conventional clock mechanism, either electrical or mechanical, for actuating the calendar drums.

In the drawings:

Fig. 1 is a front view of a combination clock and calendar embodying my invention.

Fig. 2 is a plan view of the same.

Fig. 3 is a transverse, vertical sectional view taken in the plane of the line 3-3 of Fig. 1.

Fig. 4 is a horizontal sectional view taken'in the plane of the line 4-4 of Fig. 3.

Fig. 5 is a vertical sectional view of part of the mecllanism, taken in the plane of-the line 5-8 of Fig.

. Fig. 6 is a vertical sectional view taken in the plane of the line 66 of Fig. 4.

Fig. 7 is a horizontal sectional view taken in the plane of the line 1-1 of Fig. 3.

Figs. 8 and 9 are horizontal sectional views taken in the plane of the lines 8-4 and 8-9 of Fig. 6, showing part of the drum operating means. a

In that embodiment of the invention shown in the drawings, the casing which encloses the clock and calendar parts comprises a front wall l0 having a median curved portion, a rear wall ii, side walls l2, l2, and a top I! hingedly connected to the rear wall H by hinges H.

The bottom I! is preferably integral with an upwardly extending wall l6, which is adjacent the inner surface of the rear wall Ii, and a horizontally disposed wall I! which forms an inner top or cover for the clock and calendar mechanism. The walls ii and II are slit at H, as best shown in Figs. 3 and 4, to permit the metal or other material of which said walls are made to be bent inwardly to form the horizonial partition I! which serves as a support for parts to be described. The portions, i6, and I! are secured to the main casing by any suitable means.

Within the chamber formed by the casing, between the inner cover I! and bottom i5, is a series of drums, preferably four in number. As

shown, the drum 20 carries on its. periphery numerals and vertical division lines indicating hours and five minute intervals, the drum 2! carries on its periphery the names of the days of the week, the drum 22 carries on its periphery the 5 names of the months, and the drum 23 carries on its periphery the numerals l to 31, inclusive, for indicating the day of the month. The markin s on the drums and the number and location of the drums may be varied. Each drum prefl0 erably comprises a flat, centrally apertured, circular member provided with an upwardly directed flange which constitutes the periphery on which the hour, days of the week or month markings are carried. 15

A rectangular casing 24 is secured by screws 25 to the under side of the cover IT. The casing 24 contains conventionalclock mechanism, only partially shown, for rotating the shaft 26 which depends from the casing. As shown, there is pro- 20 vided a spring winding device 21, such as used in mechanically operated clocks.

The lower end of the shaft 26 is journaled in a bearing 26' mounted in the support H. The drums 2|, 22 and 23 are loosely mounted on a 25 shaft 28 non-rotatably mounted in the bottom I 5 and bearing 26'. The drums are supported in properly spaced positions on the shaft 28 by coilars 28f fixed to the shaft.

The drum 20 has fixed to it a flanged collar 29, 30 to which is fixed a gear 30, the collar being loosely mounted on the shaft 26. The shaft 26 has keyed to it a pinion 3i which meshes with a gear 32 on a-vertical shaft 33 depending from the casing 24 and operatively connected within the cas- 35 mg to the clock mechanism for operating said mechanism. On the shaft 33 is a second, smaller gear 34 which meshes with the gear 30 on collar 29, for rotating the drum 20. The gearing is designed so that the drum 20 makes one revo- 40 lution in twelve hours.

The gear 34 meshes with a gear 35 fixed to a vertical shaft 36 depending from and supported by the wall IT. The shaft 28 also carries a pinion 21 in mesh with a gear 38 fixed to a rotatable. 5 stub shaft 38. The shaft 39 "has fixed to it two discs 40, 4|, provided with contact members 42, 43, respectively. The shaft 39 makes one complete revolution in twenty-four hours.

The contact members 42 and 43 are of difier- 50 ent peripheral lengths. The contact member 42 engages a friction wheel 44 fixed to a rotatable shaft 45 Journaled in the frame members I! and I1. Said'shai't 45 has fined to it a friction wheel 48 which has frictional engagement with the mounted, and operative connections between said shaft which is parallel to the driven shaft and the drums of said series for actuating the same in predetermined relation to the speed of rotation of the drum which carries the hour and minute designations to permit certain of said designations to be observed through the openings in said casing. i

6. A combination clock and calendar comprising a casing having a plurality of openings, clock mechanism in the casing, a driven shaft projecting from the clock mechanism, a drum carrying hour and minute designations loosely mounted on said shaft, a gear connected to the drum, a shaft parallel with the driven shaft, a gear on said parallel shaft operatively connected with the driven shaft, means operatively connecting the gear on the parallel shaft with the gear on the drum for rotating the drum, a series of drums carrying day of the week and day of the month designations, a stub shaft aligned with said driven shaft and on which the drums of said series are loosely mounted, and operative connections between said shaft which is parallel to the driven shaft and the drums of said series for actuating the same in predetermined relation to the speed of rotation of the drumwhich carries the hour and minute designations to permit certain of said designations to be observed through the openings in said casing, said operative connections comprising shafts having fixed thereon friction wheels in frictional engagement with said drums, and contact members operatively connected with said parallel shaft for actuating said friction wheelcarrying shafts part of a revolution at the end of twenty-four hours rotation of the first mentioned drum.

7. A combination clock and calendar comprising a casing having a plurality of openings inits face, clock mechanism in the casing, a driven shaft projecting from the clock mechanism in the casing, a drum mounted on said driven shaft, the drum carrying hour and minute designations on its peripheral surface, operative connections between the driven shaft and said drum for causing the drum to make two complete revolutions in twenty-four hours, a stub shaft in the casing aligned with said driven shaft, a series of drums loosely mounted on said stub shaft concentrically with said first mentioned drum and carrying day of the week and day of the month designations on their respective peripheral surfaces, and means for actuating the drums of said series.
